Project Title 

Deterioration and conservation of sandstone grottoes in Northwest China

Background & Summary of Project

Grottoes carved in sandstone are common in China. They have been exposed to the environment for over one thousand years since they were initially created. Deterioration of sandstone grottoes has been occurring through time, resulting in serious weathering phenomena such as flacking, blistering, and loss of materials. Yinghong’s project is aimed at investigating the factors that cause the deterioration and evaluating which conservation treatments could address the main problems of sandstone grottoes in Northwestern China.
